TIRE-RIM.

Application filed June 7; 1816. Serial No.'102,265.

' To all whom it may concern:

Be it known that I, HENRY Sgrmmmrrs State of Oregon, have invented new and useful Improvements in Tire-Rims, of which the following is a specification. i

This invention relates to a tire rim and particularly to that type of rim which is especially adapted for use upon the fellies of automobile wheelsand similar vehicles.-

The primary object of the invention is to provide a tire rim of this characternhaving an outer section which is removably connected with an inner section fixed to the wheel felly thus enabling the tire to be easily and quickly connected with or disconnected from the wheel to which the rim is applied.

Another object ofthe inventionns to pro-' vide the inner section of the rim which is fixedly connected with the felly with diagonally disposed and circumferentially arranged ribs on its outer face adapted to be received in grooves formed by similar ribs arranged in pairs on the inner face of the outer section thus preventing the sections from becoming separated through lateral movement when i in. tire clamping position.

A further object of the invention 1s to of the t1re rim Wlth' tapered lugs which co-actwith an inclined portion on-the inner section of the rim in to provide the outer an upstanding flange which closes a space- 40 causing the outer or removable section of theriln to be tightly wedged between the inner section and the tire when said rims are in tire clamping position.

I A still further object of the invention is section of the rim with formed by the tapered ribs on said sections and is engaged by latch members on the 1nnsr section of the rim to prevent turning movement of the outer section of the rim 'when said sections are in tire clamping position.

\Vith these and other objects view, the invention resides in the novel combination and arrangement of parts which will be hereinafter described v and particularly pointed out in the claims.

The preferred embodiment of the 1nven-. tion has been illustrated in the accompany- 111g drawing although no restriction is nee-- essarily made to the precise details of con- Struction'there 'n shown, as changes, alterations, and modifications within the scope of the clalms may be resorted to when desired.

Patented Apr. 24, 1917.

Like characters of reference denote corresponding parts throughout the several views in the drawing, in which:

Figure 1 is a face view of a felly showing the improved tire clamping rim connectedtherewith.

Fig. 2 is' a transverse sectional View through the felly and rim and showing the same upon an enlarged scale.

Fig. 3 is a perspective view of a portion of the inner sect-ion of the tire clamping Fig. 4 isa similar view of a portion of theoute'r section of the tire clamping rim.

Fig. 5 is a detail View partly in' section of I a portion of the felly and tire clamping rim showing the manner of locking the outer rim sectlon agalnst turning movement.

Referring-now to the drawing in detail,

the numeral 1 designates the felly of an automobile wheel of the type now in com mon use and having a beveled outer face 2.

The improved t1re clamping rim is designated in the drawing by the numeral 3 and.

comprises an inner section 4 and an outer section 5. I

The inner section 4 is provided for the greater portion of its width with an inclined and reduced portion 6 forming be tween the marginal edges of said section on the outer facethereof a continuous shoulder 7.

The inner face ofthe'inclined portion 6 of the inner section 4: is adapted .to be brought 'into contact with the beveled face on the"felly 1. said section being connected withthe felly by means of bolts 8 and has forum-d therein an opening 9 registering with a similar opening 10 in the felly 1 and through which may be passed. the valve stem on the tire.

. One marginal edge of the inner section 4 isprovided with acurved flange forming a continuous tireclamping bead ]1.'- The ranged a locking pin 13 having .a length greater than the thickness ofthe reduced and inclined portion of said section. Leaf springs 14 have one end connected with'ond end of a pin l3and itsother end secured to the inner face of the inclined portion 6 of the inner section, so that said pins for a portion of their length extend below the outer face of the inclined portion on the inner section.

Arranged circumferentially about the outer face of the reduced portion 6 of the inner section 1 are spaced ribs 15 which extend diagonally and transversely of said portion between one marginal edge thereof and the shoulder. 7, said ribs gradually decreasing in height from the marginal edge toward the shoulder 7.

The outer section 5 of the tire rim has formed thereon at one marginal edge a curved flange forming a continuous tire clamping bead 16, the other marginal edge of said section being adapted for contact with the shoulder 7 when the sections are in tire clamping position.

The inner face of the outer section 5 is provided with diagonally and transversely disposed ribs 17 arranged in pairs circumferentially about the tire to provide between each pair of ribs a groove 18 adapted to receive a rib 15 on the inner section of the tire rim, said ribs 17 gradually increasing in height from the marginal edge of the section adapted for contact with the shoulder 7 toward the bead 16.

The bead 16 on the outer section 5 merges into an upstanding flange 19 on the inner face of the outer section 5. said flange being arranged at the larger ends of the ribs 17 and forms a shoulder with which the larger ends of the ribs 15 on the inner section of the tire are adapted to contact when the sections are in tire clamping position.

The flange 19 has formed therein at diametrically opposite points openings 20 which serve as sockets to receive the projecting portions of the pins 13 when the sections are in the clamping position thus locking the outer section against turning movement and also enabling the flange 19 to close the space between the inner and outer sections at the large end of the ribs thereon.

By forming. the inner section of the tire clamping rim with an inclined portion and tapering the ribs on said sections. the outer sect-ion of the rim is caused to'be tightly wedged between the tire and the inner sec,- tion of the rim when the outer rim section has been turned to tire clamping position, thus securely engaging the rim with the tire and also exerting a slight binding action between the rim sections to prevent undue strain being imposed on the pins 13.

The outer section 5 has formed therein in its reduced portion an elongated recess :21 opening out at one end through the marginal edge of said section which is adapted for contact with the shoulder 7 and with the side walls of the recess running parallel with the adjacent ribs 17 to ena le the outer BEST AVAILABLE COP section to be connected with the inner section without injuring the valve stem assing through the inner section and the fe ly 1.

lVhen 'it is desired to use the rim in connection with a felly as shown in the drawing, the inner section of the tire rim is secured thereto in the manner described and the valve stem passed through the opening in the telly and section 4.

The bead on the tire is positioned in the tire clamping bead 11 and one marginal edge of the outer section 5 disposed between the other bead on the tire with the grooves I 18' formed by the ribs 17 in a position to receive the larger ends of the ribs 15.

The outer section 5 is now turned to cause the ribs 15 to pass through the groove 18 and when this has been accomplished the bead 16 will be brought into contactwith the head on the tire and the extending portions of the pins 13 on the section 4 received in the sockets in the flange 19, so that the outer section is locked againsttnrning movement, while the ribs on said sections hold the outer section against lateral movement and in tire clamping position with the flange 19 excluding foreign matter from the spaces between the ribs on said sections.

It will also be noted that the Qop shoulder 7 on the section 4 limits the inward movement of the outer section so that the sockets in the tin nge 19 will always be caused to register with the extending portions of the pins 13 when the sections are moved to tire clamping position.

When it is desired to remove the tire from the wheel. the springs connected with that locking pins are moved to a position to m tract the portions of the pins from sockets 20 and the outer section of the rim turned to disengage the ribs 15 from the grooves 18 formed by the ribs 17 at which time the tire may be disengaged from the bead 11 on the inner section 1.

From the above description. taken in connection with the accompanying drawing. it is at once apparent that a tire clamping rim has been provided which is simple in construction.inexpensive of manufacture, vct

highly etticientin use.

Having thus described the invention, what is claimed as new. is:

1. In combmatlon, a felly havmg a beveled outer face, a run having an inner section connected with said face, tapered tn; 1

on the inner rim section. an outer rim section for connection with the inner rim section, and tapered ribs on the outer rim sew tion arranged in pairs to provide gnmves to receive the ribs on the inner rim secthm.

2. In combination. a fell having a Lie. eled outer face, a rim having an inner section provided with a reduced and i'mrcllimmd portion connected with Slit] fitt. maiyuuutc ribs on the outer face of said imdlimmll air arranged and transversely extending tapered ribs arranged in pairs on the inner face of the outer rim section to recelve therebetween the ribs on the inner rimsection.

3. In-combination, a felly having 'a bev-' eled outer face, a rim having an inner section connected with said face, diagonally disposed andtransversely extending tapered ribs on the outer face of the inner section, an outer rim section for connectlon with the inner rim section, diagonally disposed and transversely, extending tapered ribs arranged in pairs on the inner face'of the outer rim section to receive therebetween the ribs on the outeroface of the inner ri'm section, a. flange on the outer rim section hev 'ing openings therein,-and spring pressed pins carried by the inner rim section and having portions thereof adapted to be received in said openings.

In testimony whereof I affix-my signature.
